      A problem of gas seepage into the vacuum in case of spherical and cylindrical symmetry is considered. The convergence rate of characteristic series was experimentally studied there. Acceleration methods for convergence of series were implemented; the values of gas dynamic parameters were produced with high accuracy both for the case of the cavity implosion and for the case of the gas seepage from the ball (cyllinder). The provided results can be used as references when solving gas dynamic problems with difference methods.
